Why Do I Need a Percolation Test?

Perc tests determine the right and wrong locations for a septic system, and they're often required by local jurisdictions before a new one can be built or an old one replaced. That's because septic tanks work by holding wastewater long enough to naturally separate liquids and solids.

Do I need a percolation test?

When is a percolation test needed? A percolation test should always be performed BEFORE installing a new soakaway system, or when replacing an existing one (which is usually sited in a different location to the existing soakaway).

What is percolation and why is it important?

Percolation can be used to predict water transport factors such as the rate of leaching, or the flow of materials into water. This is most often used in agriculture to determine the movement of fertilizers or the salt content of soil.
